Three-phase ON-OFF cam switch, 4 poles 25A for inductive loads (electric motors) and general control. 90º rotary knob, with two 0-1 positions. DIN rail mounting, suitable for both vertical and horizontal mounting.
The rotary cam switches of the D0/8 series offer compact size and excellent quality, manufactured in Germany according to the strictest European and international standards to meet all safety requirements. These switches are characterized by easily accessible captive Phillips screws. Thanks to the different contact systems and materials, they are suitable as control and motor switches as well as for use in electronic circuits.Active parts protected against accidental contact.
This switch is suitable for three-phase motors up to 2.2kw connected to 230Vac or 5.5kw connected to 400Vac.
